so i was fixing to eat this guy on a kx250, and then all the sudden, BAM!!! i hear something that doesnt seem right..and my bike wont move any...so i look down and my Tallon 49 tooth gold rear sprocket has blown off! and scrapped the crap out of my black rim too! so i ripped the shreded sprocket off, and pushed my bike back to the pits..pissed off.. anyway...if in wouldnt have had tallon hubs on it.it woulda blown off..but im still shocked, how did this happen? i sheared off allll the bolts that hold the sprocket on. and ripped the sprocket to trash, and bent it all up, my wheel is perfectly lined up and everything..this suck!! any suggestions?
